unus、Definition of galvanized square tube
Galvanized square tube is a square steel pipe treated by hot dip galvanizing or cold galvanizing process。It uses hot rolled or cold rolled galvanized steel strip or galvanized coil as raw material，After cold bending processing and forming，Yüksek frekans kaynağı veya sıcak dip galvanizing tedavisi yapıldı.。
duo、Proces productionis
Galvanizatae tubae quadraticos in calore dipo galvanizatae tubae quadraticos et tubas quadraticos galvanizatae sunt：
Tum calidus galvanizatus tuba quadrata：
Stellae aut punctos in formam et in tubas quadratas erunt，tunc disperse eam in bano calore vanitante，Forming a zinc layer through a series of chemical reactions。
Processo productionis simplex，High production efficiency，Suficit parvi fabrii producere。
Estne bona fortitudo、resilience、Plasticitate et perfectione ferentia，PropertyName。
Cubica galvanizata quadrata frigida：
Laera cinca coating on the surface of square tube through electrochemical principle，Mainly relying on electroplating technology。
The galvanized layer is relatively thin，Ama yüzey yumuşak.、etiam，Superior anti-corrosion performance，Sufficiens occasionibus cum altis anticorrosionis requiribus。
